The room is as good as a room in a guesthouse. Very spacious. You won't find better with the same price. Indeed, the price is very interesting.
I really recommend it.
The neighbourhood is not interesting. It's under construction. Not a lot of things to eat compared to other places that we visited. BUT the room is near Bang Wa BTS station, so it's very convenient !
When I go to Bangkok again, I will rent this room again.
